In the context of recent debates about same-sex marriage, consensually nonmonogamous (CNM) relationships have recently begun making their way into media discussions. In the current research, we investigated whether stigma is attached to these nonnormative romantic relationships and, conversely, whether halo effects surround monogamous relationships. In Study 1 we analyzed openended responses to the question "what are the benefits of monogamy?". The most commonly mentioned benefits included the promotion of commitment and health (especially the prevention of sexually transmitted infections [STIs]). In Study 2, descriptions of CNM relationships were strongly stigmatized and a substantial halo effect surrounded monogamous relationships. Specifically, monogamous relationships were rated more positively than CNM relationships on every dimension (both relationship-relevant and arbitrary relationship-irrelevant factors) that we examined and across diverse social groups, including CNM individuals themselves. In Study 3, we conducted a person perception study in which participants provided their impressions of a monogamous or a CNM relationship. The monogamous couple was rated overwhelmingly more favorably than the CNM relationship. Finally, in Study 4, we replicated the findings with a set of traits that were generated with regard to relationships in general (rather than monogamous relationships, specifically) and with a broader set of arbitrary traits. Across all studies, the results consistently demonstrated stigma surrounding CNM and a halo effect surrounding monogamy. Implications for future research examining similarities and differences between monogamous and CNM relationships are discussed. One man and one woman, united in lifelong and faithful love, leading to new life in children-whenever and wherever it was in danger.. . And now we ring the steeple bell

In this article, we critically examine the social institution of monogamy. First, we discuss the lack of an adequate and consistent definition of the construct of monogamy and consider how common monogamy is. Next, we address perceived benefits of monogamy and whether those ostensible benefits are supported by empirical evidence. We conclude that evidence for the benefits of monogamy relative to other relationship styles is currently lacking, suggesting that, for those who choose it, consensual non-monogamy may be a viable alternative to monogamy. Implications for theories of close relationships are discussed.

We proposed that the premise that monogamy is the exemplary form of romantic partnership underlies much theory and research on relationship quality, and we addressed how this bias has prompted methodological issues that make it difficult to effectively address the quality of nonmonogamous relationships. Because the idea that consensually nonmonogamous (CNM) relationships are functional (i.e., satisfying and of high quality) is controversial, we included a basic study to assess, in a variety of ways, the quality of these relationships. In that study, we found few differences in relationship functioning between individuals engaged in monogamy and those in CNM relationships. We then considered how existing theories could help researchers to understand CNM relationships and how CNM relationships could shed light on relationship processes, and we proposed a model of how CNM and monogamous relationships differ. Finally, in a second study, we determined that even researchers who present data about CNM are affected by the stigma surrounding such relationships. That is, researchers presenting findings favoring polyamory were perceived as more biased than researchers presenting findings favoring monogamy.

In our target article, "The Fewer the Merrier: Assessing Stigma Surrounding Consensual Nonmonogamous Relationships," we documented a robust stigma toward consensual nonmonogamous relationships and a halo surrounding monogamous relationships. In the present piece, we respond to six commentaries of our target article with the aim of promoting future research and policy change. First, we address questions and concerns raised by commentators using existing data and found that regardless of perceived relationship happiness, sexual orientation, or gender (of experimental targets), individuals in consensual nonmonogamous relationships were more negatively viewed on a variety of qualities (both relationship-specific and nonrelationship specific) compared to those in monogamous relationships. Second, we suggest productive future research avenues with regards to implications for social change, and strengthening methodology used in consensual nonmonogamous research. Finally, we consider common ground among the commentators as an avenue to promote coalition building through the examinations of prejudice toward individuals in nonnormative romantic relationships. We conclude that this is only the beginning of a fruitful line of research and argue that the stigma toward departures from monogamy is robust and, of course, worthy of additional research.
